我最近购买了一块二手开发板来开始工作。我设法使用启用了 Mendel 5 (Eagle) 的 SSH 来刷新它，并按照入门说明进行操作，直到我尝试了演示。
我根本无法让它工作！
如果我运行 edgetpu_demo --stream
我得到：
shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
Press 'q' to quit.
Press 'n' to switch between models.
Traceback (most recent call last):

以root身份运行给了我：
shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
Press 'q' to quit.
Press 'n' to switch between models.

这似乎更接近，但不知道如何解决。我已经尽可能多地进行了搜索（将用户添加到plugdev，确保所有内容都正确安装）
有任何想法吗？很确定如果这不起作用，某些东西就会被破坏。
